Peacebuilding and Peace Support Office

Harnessing capacities globally in the service of conflict prevention and sustaining peace

 

As part of the Departments of Political and Peacebuilding Affairs and Peace Operations (DPPA-DPO), the Peacebuilding and Peace Support Office (PBPSO) serves as a facilitator to enhance coherence and collaboration across the UN system and with partners in support of nationally owned efforts to build and sustain peace. Established in 2005, PBPSO draws together expertise to advance impactful system-wide action, policies and guidance and fosters an integrated and inclusive approach to prevention and sustaining peace.

 

The Office comprises the Peacebuilding Commission Support Branch, the Financing for Peacebuilding Branch and the Peacebuilding Strategy and Partnerships Branch. Led by Assistant Secretary-General, Elizabeth Spehar, PBPSO assists and supports the Peacebuilding Commission (PBC) with strategic advice and policy guidance, manages the Peacebuilding Fund (PBF) on behalf of the Secretary-General, and works to enhance system-wide coherence and partnerships with UN and non-UN actors in support of building and sustaining peace in partner countries.

"The new peace and security architecture is more integrated, with our Peacebuilding Office serving as a hinge between peace and security and development."
